Is the performance also suffered due to sox11 driver? I am not sure
if TPS on X uses sox11 driver. But we are testing TGS's Figaro (a
PHIGS implementation on top of starbase by Template Graphics System)
on X and notice that when sox11 driver is used, the mouse performance
in Figaro (starbase) window is poor. This is on an HP9000/370CH.

I think it is generally true that when you build on top of lower layer
software, the performance won't be as good. I am looking for HP's own
PHIGS (built on the same level as starbase) or even better PEX? Where
are they? :-(
